Digital asset market update — 23 August 2026

The digital asset market experienced significant capital inflows and notable protocol developments. Bitcoin and ether ETFs recorded their strongest inflow week since October, attracting $2.6 billion, and saw combined trading volume triple to $29 billion, despite both assets remaining negative on the year (The Block). This surge followed a pronounced rally, with Bitcoin reaching nearly $80,000, partially attributed to a Treasury buyback tweak that helped reduce long-term yields and triggered a record short squeeze in a bearish market (CoinDesk). These developments highlight increased institutional engagement and capital allocation into exchange-traded products.

Zcash (ZEC) emerged as a major focus, with its price reaching an eight-year high near $850. This rally was fueled by speculation surrounding a Grayscale spot ETF push and substantial futures activity, which saw nearly $10 billion in 24-hour futures volume and $1.76 billion in open interest (The Block, CoinDesk). The Grayscale filing indicated progress toward converting its Zcash Trust into a spot ETF, drawing comparisons to the 'next bitcoin' (CoinDesk).

In market infrastructure news, Solana reduced its mainnet slot time to 350 milliseconds, an initial step toward a 200-millisecond goal. This change aims to accelerate transaction confirmations but is not intended to increase overall network throughput (The Block). Security concerns arose for Web3 gaming network Sandbox, which halted bridging on Base and BNB Chain following an exploit. The company isolated tokens and warned users against trading SAND on the affected networks, noting an impact of under 0.01% of supply (CoinDesk).

Separately, the crypto exchange BitMart is considering a partial restart and creditor payouts weeks after announcing its shutdown, engaging White & Case as restructuring counsel with a roadmap expected by September 9 (CoinDesk). Regulatory challenges persist in prediction markets, as Kalshi faces restrictions in multiple states while battling the development in court and contending with the CFTC's pursuit of new rules (CoinDesk). Fairmint CEO Joris Delanoue warned that tokenized stocks could risk recreating Wall Street’s 1960s ‘paper crisis’ due to fragmented systems and standards, highlighting a potential systemic risk (CoinDesk).

Institutional participants will likely monitor the progress of the Grayscale Zcash ETF conversion.
